Heavy-Duty Extension Cable for Network Devices That Require a Heavy-Gauge Connection. This 10-foot extension cord features 14 AWG wire suitable for high power connections, making it a reliable solution for large server applications that require a higher-rated, heavier-gauge cable. It can be used to connect a computer, server or other device with a NEMA 5-15P plug to a PDU, UPS system, surge protector or wall outlet with a NEMA 5-15R outlet. The 10-foot length allows you great flexibility in placing equipment with respect to the power outlet. Right-Angle Plug Makes Connecting in Tight Spaces Easier. The space-saving right-angle NEMA 5-15P connector is easy to install in confined spaces, such as behind your computer desk or workstation. The right-angle construction also relieves strain on the cable and connector and prevents the cable from bending awkwardly.
